Hi, I rent my ensuite room (with private bathroom inside) into a flat located in Smithfield Market. My flatmate is sharing the flat and will be able to give you the keys. The location is very convenient (15min walking to Temple Bar, 5min by tram).
As you can see it is a spacious an luminous room with a double bed, you can also use the hanging wardrobe. The room is perfect for a couple or a single person on hollidays.
